The ADP1706/ADP1707/ADP1708 are CMOS， low dropout linear regulators that operate from 2.5 V to 5.5 V and provide up to 1 A of output current. Using an advanced proprietary architecture， they provide high power supply rejection and achieve excellent line and load transient response with a small 4.7 μF ceramic output capacitor. The ADP1706/ADP1707 are available in 16 fixed output voltage options. The ADP1708 is available in an adjustable version， which allows output voltages that range from 0.8 V to 5.0 V via an external divider. The ADP1706 allows an external soft start capacitor to be connected to program the start-up time; the ADP1707 and ADP1708 contain internal soft start capacitors that give a typical start-up time of 100 μs. The ADP1707 includes a tracking feature that allows the output to follow an external voltage rail or reference. The ADP1706/ADP1707/ADP1708 are available in an 8-lead， exposed paddle SOIC package and an 8-lead， 3 mm × 3 mm exposed paddle LFCSP， making them not only very compact solutions but also providing excellent thermal performance for applications requiring up to 1 A of output current in a small， low profile footprint.
